The Declaration of Independence
All men are created equal and there are certain unalienable rights that governments should never violate. These rights include the right to life liberty and the pursuit of happiness. When a government fails to protect those rights, it is not only the right, but also the duty of the people to overthrow that government. In its place, the people should establish a government that is designed to protect those rights. Governments are rarely overthrown, and should not be overthrown for trivial reasons. In this case, a long history of abuses has led the colonists to overthrow a tyrannical government.
